Anand and I just spent some time playing with NVIDIA's recently announced Project Shield, which is NVIDIA's portable handheld gaming device home to the also just-announced Tegra 4 SoC (4x ARM Cortex A15). I came away pretty impressed with Project Shield ergonomics after initially going in very skeptical (like GPU editor Ryan Smith) about how 38 watt-hours (这电池容量和很多laptop差不多了吧)of batteries, a display, Tegra 4, and all the accompanying hardware could possibly feel comfortable stuffed into what boils down to a game controller.

There is indeed a fan inside（A15 fanless失败？）, albeit a small one. NVIDIA says it won't come on all the time during normal use, and after playing a few Android games natively (Hawken) on the device this seemed to be the case.

有扇子也不稀奇，这玩意是游戏机，时时最高频率满负荷运行，跟手机有点区别

nv的TESLA还有FANLESS的

我的意思是 性能功耗不可兼得
和core相比
所谓A15性能牛b功耗很低是不可能的。

没什么不可能，酷睿刚出来的时候，性能秒飞P4，功耗远低于P4

哦 我忘了说和谁做对比
我是说A15和core对比，性能高于core，功耗小于core是不可能的。
